blazing spade Have you learnt sum and profucts of roots of quadratics yet?

cant understand this brain lagging

#

Uhh

#

Wait.lemme show u a picture

#

To make.you less confused

#

#

ya know this

blazing spade Mar 21, 2024, 6:00 AM

#

Yesh

#

Yeah*

#

So try to use this to solve

#

( I'm gonna use a,b instead of alpha, beta henceforth )

#

Using vietas theorem, we can infer from the second equation ( 9x²+hx+1=0)
That a²b²=1
Or, ab=±1

Oh ok nvm

#

Well factorise it

#

Using the quadratic formula, or splitting middle term or completing the square

#

Whichever method you guys have learnt

#

after moving all the terms to 1 side

analog vault Mar 21, 2024, 6:05 AM

#

in 14(i)

#

a+ b = 3/2

#

ab = 2

blazing spade Mar 21, 2024, 6:07 AM

#

No no you don't need to use that you can factorise it normally

analog vault Mar 21, 2024, 6:07 AM

#

Ok

I saw the 13th one underlined so I thought you needed help w that

blazing spade I saw the 13th one underlined so I thought you needed help w that

it was done so I marked 💀

#

0.75 is 1 root

blazing spade Mar 21, 2024, 8:14 AM

Other is?
